Specification of Letters Pa e. t t 4, 1915 Application filed October 19, 1911, Serial No. 655,497. Renewed May 19, 1915. Serial No. 29,223.

I '0 all whom it may concern:

Be it known that I, WILLLAM J. RUMPLE, of the city of Omaha, county of Douglas, and State of Nebraska, have invented certain new and useful Improvements in Machines for Making Pastry, which improve-i ments are described in the following specifi cation and are illustrated by the accompanying drawings.

The invention relates in general to machines for molding and baking pastry of various kinds, and in particular to icecream cone machines, so called, of that kind in which pairs of co-acting dies mold a plastic batter into the form of hollow .receptaoles for icecream, and hold the same in that form while baking.

, It is the object of the invention to open I and close the female dies of such a machine by sliding separable sections of those dies horizontally in opposite directions; to unite the separable sections of the female dies elastically, when they are brought together; *toapply the batter in the first instance to the male dies alone, and to receive the drippings,

rable sections of the female dies; to pro-- duce in such a machine a regulated mixture of combustible gases as fuelfor the baking; to bake all parts of the individual pastry cones uniformly, without inverting or otherwise changing the position of the dies for that purpose; to increase the capacity and efficiency of such machines; and in general to produce a superior machine of the specified kind. To accomplish this object I incorporate in my improved machine for molding and baking pastry a plurality of dependent male dies carried by a vertically reciprocable frame, and a plurality of subjacent axially split female dies mounted on a horizontal track.

The best manner in which I have contem+ plated applying the principles of the invention, 1sshown in said drawings; but, as many changes can be made in the constructron of the machine, and many apparently d fi'erent embodiments of these principles, wlthout departure from the scope or spirit of the lnvention, it is intended that all matters contained in the following description, or shown in said drawings, shall be interpreted as illustrative and not in a limiting sense. a

Figure 1 is a side elevation of an icecream cone machine that is constructed in accordance with the principles referred to. Fig. 2

is a front elevation of the same machine.

Fig. 3 is a plan of the vertically reciprocable frame carryingv the male dies. Fig. 4 is an :enlarged side elevation of parts of Fig. 1,

including a single pair of dies,-male and female, shown in vertical axial section. Fig. 5 is a detail, being avreverse side elevation of parts of Fig. a. Fig. 6 isv also a detail, including a vertical section of two female dies, wide open as for discharging cones after baking. Figs. 7 and 8 are an elevation and a plan respectively of a separable section of the female split die'on the horizontal track. Fig, 9 is a detail, including an axial section of the male die in a modified form.

In the machine which is shown in the first eight figures of these drawings, a plurality of male dies, or formers, 1, being solid me tallic cones, pointing downward and provlded at the top with peripheral annular shoulders 2, are fastened by screws 3 to the underside of the horizontal and parallel iron crossbars 4 of the vertically reciprocable rectangular die-frame 5. On this die-frame are also mounted a number of burners 6, connecting with the fuel-pipe 7 and having numerous mouths, or orifices, 8, opening downward toward the male dies respectively. This die-frame is kept horizontal by its four vertical legs 9, which are slidable up and down in the tubular corner posts 10 of the main frame 11; and carries centering pins 12, which are adapted to cooperate with the dowel holes 13 in the female dies.

The mechanism for raising and lowering the die-frame 5, comprises the hand-operated lever 15, the rockshaft 16 which is worked by that lever, the counter rockshaft 17 which is connected by the sprocket wheels 18 and the sprocket chain 19 to move in 33, as shown in Figs. 7 and 8.

unison with the rockshaft 16, the rockarms 20 which are carried by said rocksh-afts, and the duplicate links 21 which connect said rockarms with the four corners of the dieframe respectively.

Each of the female dies, being divided ina vertical axial plane, comprises a pair of separable die-sections, or half-dies, 22, slidable to and from each other on the horizontal track 23, which is part of the main frame 11. Each of these die sections is a metallic shell, of general rectangular form, comprising the flat top and bottom plates 24, the vertical end walls 25, and the intermediate web, or face-plate, 26, in which are sunk a number of half-conical concavities 27, registering with like concavities in the adjacent die section of the same pair. \Vhen the correlative die sections are moved into contact with each other, the conical concavities formed between them are co-axial with the male dies respectively, as shown in Fig. 4; and when the male dies have penetrated these eoncavities to a suitable depth, the shoulders 2 impinge upon the flat top of the female dies, as shown in the same figure.

In the hollow back of each die section is placed a fuel pipe 28, branching into burners 29, whose orifices, jets or nozzles, 30, are directed toward these coneavities. Also in the same hollow back of each die section 22 is mounted a tension rod 31, which is provided with an adjusting screw 32, and operates to push apart or to draw toward each other the end Walls 25 of the die sections for the purpose of preventing and of counteracting, as occasion may require, the tendency of the die sections to warp or bend when heated; to facilitate the straightening function of this tension rod the top plates and the bottom plates, 24, are cut by slots The mechanism for operating the female dies on track 23 comprises a pair of horizontal bars 34 and 35, bolted to the alternate die sections 22 respectively, the two racks, 36 and 37, carried by those bars, a pinion 38, engaging those racks, a rockshaft 39 carrying this pinion, and a hand-lever arm 40 for operating this rockshaft. For the purpose of locking the die sections together when the female dies are closed, this rockshaft 39 carries a loose ratchet wheel 41 and a fixed rockarm 42 which have a yielding engagement with each other by means of the terminal eye 43 of that arm, the lugs 44 on that wheel, the screw rod 45 held by said lugs and playing in said eye, and the coiled spring 46 on said rod. The pawl 47 is actuated by the counterweight 48 to engage this ratchet wheel in the position shown in Figs. 4 and 5, and thereby to lock the die sections together, and is operated by hand to release the ratchet wheel, and thereby to permit the die sections to be separated from each other as shown in Figs. 1 and 2. The stationary horizontal crossbars 49, being mounted onthe main frame in sliding contact with the flat tops of the separable dic sections, are adapted to act as strippers to loosen the baked cones from the female dies, as occasion may require, and as scrapers to free the latter from adhering pastry, while those dies are being opened to the position shown in'Fig. (3. The truck 50, having wheels 51, and containing the batter that is to be molded and baked, is open at the top and is movable by hand on the horizontal track 52 to andfrom the positions shown in Figs. 1 and 2. All desired mixing of air and gases for burning is effected in the fuel chamber 53, to which those fluids are admitted under all necessary pressure and in regulated proportions and quantities through supply pipes that are not shown in the drawings. From this chamber the fuel is'conducted through the flexible pipes 54 and the telescopically extensible pipe 55 to the fuel pipes 28 and 7 respectively. The inclined chute 58 has at the top a flaring mouth, or hopper, fastened to the track rails23 and open upward immediately under all the female dies.

In that modification of my invention which is shown in Fig. 9, the male die 1 is hollow,thc c'rossbar4has a vertical perforation 56 over the middle of that die, and the burner 6 has a tubular jet, or nozzle, 57, which, reaching down through that perforation, conducts the gaseous fuel into the middle of the die, and heats the latter, in each instance, by the flame which is produced in its hollow interior.

In using this machine, the operator, by depressing lever 15, raises the frame 5 to the position shown in Figs. 1 and 2; then, by raising the lever 40, brings the female die sections together in pairs, and locks them in that position, as shown in Figs. 4 and 5; then runs the batter truck to a position directly under the male dies, as shown in Fig. 1; then, by raising lever 15, dips those dies into the batter in that truck; then, by lowering that lever, lifts these dies and the adhering batter out of the batter truck; then removes the latter 1) hand from the vertical path of the die-f i'ame 5, as shown in Fig. 2; in which position of affairs the drip from the male dies is caught in the female die; meanwhile heats all the dies, male and female, by lighting all the gas-jets and nozzles; then by lever 15 lowers the male dies and adhering batter into the female dies, where they are stopped by the contact of the shoulders 2 of the male dies with the top plates 24 of the female dies,-

closed and looked as described; at the same time, by the annular groove and peripheral cutting edge on the underside of these shoul ders, so impinging upon these top plates,

Bil

as shown in Fig. 4, he cuts off the surplus batter, if any, which has been carried by the male die to the mouth of the female die; then permits the batter cones between the male and the female'dies to bake until done; meanwhile permits the steam, formed in the female dies, to escape between the elastically locked die sections of each pair, opening apart automatically for that purpose; then lifts the male dies again in the manner above described; then by the use of lever 40, slides the female die sections apart, as shown in Figs. 2 and 6, and thereby permits the baked cones to drop into the subjacent chute 58, by which they are conveyed from the machine.

If any of the baked cones should adhere to the inside of the female dies, and hesiscribed, such adhering cones are pushed free from the female dies by the stripper 49.

Or the male dies, when lifted but slightly in the female dies, will pull the baked cones from the separating die sections.

The combined hopper and chute 58 not only transfer the finished pastry from the 1nachine,but also save fuel by preventing wasteful dissipation of heat from the dies immediately above.
